Looking for a manga

Hi guyz I've been looking for a manga that I read before but cant seem to find it, please please help

As far as I remember they are in Highschool and probably childhood friends or what....that seme is big and bulky since I think he is in judo club or what, and the uke is more like a tsundere, he has this small knife with him. And there this scene a misunderstanding where the seme thought uke sleeps with other guys but not, and the uke like "don't get close to me or what" while holding the knife hahaha can't explain it but its just like that....... there was also a scene where the uke tells to the seme to stop bulking since he's getting bigger...... can't remember much the genre and i don't know if it was a doujinshi or what but it does has more that 3 or 5 chapters I guess
